Apache gets a boost in the latest Netcraft survey, now powering 68.60% of the active sites on the Internet.
During 2001 and the first half of 2002 several companies hosting very large numbers of hostnames including Webjump, Namezero, Homestead, register.com and Network Solutions migrated to Microsoft-IIS. Subsequently these businesses have either failed, significantly changed their business model, or reverted to their previous platform, and Microsoft-IIS share is now in line with its long term pre-summer 2001 level of around 20%.
Microsoft's IIS is second with a 23.44% share.
Now would be time to compare the respective amount of junk traffic, currently riddling the Internet on an ongoing basis, generated by attacks trying to exploit, or already exploiting their security holes.
